4 Radiation 2 Radiation The technology of the STMicroelectronics Rad-Hard rectifier s diodes is intrinsically highly resistant to radiative environments. The product radiation hardness assurance is supported by a Total Ionisation Dose (TID) test at high dose rate on each diffusion lot and a Single Effect Event (SEE) characterization. 2.1 Total dose radiation (TID) testing Each diffusion lot is tested in total ionizing dose at high dose rate on 10 parts housed in TO-254AA, 5 biased and 5 unbiased. The irradiation is done according to the ESCC specification, standard window. Both pre-irradiation and post-irradiation performances are tested using the same circuitry and test conditions for a direct comparison can be done (T amb = 22 ±3 C unless otherwise specified). The following parameters are measured : Before irradiation After irradiation (target 1 Mrad (Si)) After 24 hrs at room temperature after 168 hrs at 100 C anneal 2.2 Single event effect The Single Event Effect (SEE) relevant to power rectifiers are characterized, i.e. the Single Event Burnout (SEB). The tests are performed as per ESCC 25100, each one on 3 pieces from 1 wafer at room temperature. The accept/reject criteria are : SEB (Destructive mode): The diode is reverse biased during irradiation. The test is stopped as soon as a SEB occurs or when the reverse leakage current is above the specification or when the overall fluency on the component reaches 1E7 cm². PIST (Post-Irradiation STress) test: After the irradiation, a stress is applied to the diode in order to reveal any latent damage on the irradiated devices. The reverse voltage value is increased from 0 V to 100% of V R max. and then decreased from 100% of the V R max. to 0 V. At each step, the reverse leakage current value is measured. Table 5.
